A commercial medical and "natural science" museum operated by Jordan. This may have been the earliest commercial medical museum in California. Pages 50 onward describe what Jordan called the "Pathological Room, For reference and use of Medical Gentlemen and Students-only." "The wages of Sin is Death." This facility, which was presumably off-limits to women, clearly was intended to elicit guilt regarding sexuality, and to dramatize venereal disease, and "diseases caused by masturbation," and to encourage visitors to consult Dr. Jordan for a cure.
